Psychological Factors Affecting Medical Condition: A New Proposal for DSM-V

Alexithymia, intolerance to uncertainty and mental health difficulties in adolescents with Type 1 diabetes mellitus

BACKGROUND

Type 1 Diabetes Mellitus (T1DM) represents a serious chronic condition affecting a wide number of people. Discussion of the physical issues associated with T1DM pervades the literature, however, there is less discussion of the psychological consequences. Mental health difficulties, alexithymia and uncertainty are present in this population, and known to be harmful for the onset, maintenance and worsening of T1DM. This study aimed to evaluate the presence of these phenomena in people with T1DM.

METHODS

105 participants aged between 11 and 17 years old (M: 13.88; SD: 2.16) affected by T1DM were included in the sample. To assess the presence of mental health difficulties, SAFA scales (Depression, Anxiety and Somatic symptoms) were included in the protocol together with TAS-20 and IUS-12, which evaluate the presence and role of alexithymia and intolerance to uncertainty in the sample, respectively.

RESULTS

A concerning presence of anxiety, depression and somatic symptoms was found in the sample. Mental health difficulties appeared to be consistently present in the sample, often overcoming pathological thesholds. Alexithymia and uncertainty were also common, highlighting their role in T1DM.

CONCLUSIONS

Active mental health difficulties together with high rates of alexithymia and intolerance to uncertainty were prevalent in the sample of adolescents with diabetes.

Distinguishing and treating demoralization syndrome in cancer: A review

IMPORTANCE

Demoralization, characterized by a persistent inability to cope, as well as helplessness, hopelessness, and despair, is highly prevalent in oncology, with between 36% to 52% of patients exhibiting demoralization syndrome. Given established evidence linking demoralization in patients with cancer to physical symptom burden, quality of life, sleep disturbance, and suicidality, assessment and treatment of demoralization syndrome is critical for optimizing clinical and psychosocial outcomes.

OBSERVATIONS

The term "demoralization" is highly relevant to the care of patients with cancer facing life-limiting illnesses. Indeed, demoralization can be conceptualized as a feeling state characterized by the perception of being unable to cope with some pressing problems and/or of lack of adequate support from others. Despite a considerable overlap in symptoms, demoralization and depression should be regarded as distinct and independent clinical syndromes. Patients who are demoralized but not clinically depressed often describe a sense of subjective incompetence and do not report anhedonia (i.e., loss of interest and inability to enjoy things). Although the definition of demoralization is now included as a distinct syndrome in the International Classification of Diseases (ICD)-11, it has been neglected by the current U.S. official nosology in psychiatry, such as the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR). As such, demoralization syndrome may be under- or misdiagnosed and treated ineffectively in the oncology setting, potentially prolonging suffering and influencing cancer outcomes.

CONCLUSIONS AND RELEVANCE

Optimization of methods to diagnose and assess demoralization syndrome is critical to underpin rigorous studies evaluating the efficacy of psychotherapeutic and pharmacological interventions for patients with cancer experiencing demoralization. Our review supports the use of specific diagnostic criteria for demoralization in cancer patients, introduces methodological considerations relevant to treatment studies, and presents a novel measurement approach to the assessment of demoralization severity with the Clinical Interview for Demoralization (CIDE).

Dignity and Related Factors in Patients with Cancer: A Cross-Sectional Study

PURPOSE

Dignity is a basic human right that is related to psychological distress factors in patients with cancer such as depression and demoralization. Hence, the dignity issue is of great importance to healthcare professionals. The present study aimed to advise healthcare professionals regarding the related distress factors of dignity in patients with cancer by investigating its relationship with patients' demographics, disease characteristics, and psychological distress.

METHODS

This was a cross-sectional study design. A convenience sample of 267 patients with cancer from a medical center was recruited into this study. Each patient completed demographics and disease characteristics questionnaires, the Patient Dignity Inventory Mandarin Version, the Demoralization Scale Mandarin Version (DS-MV), and the Patient Health Questionnaire-9 (PHQ-9). Data were analyzed with SPSS 22.0 software.

RESULTS

Dignity was significantly correlated with age, demoralization, and depression. Cancer patients aged 65 or above were more likely to have a lower sense of dignity. In the present study, the sensitivity and specificity of the Patient Dignity Inventory Mandarin Version for demoralization (DS-MV≥30) were 84.8% and 79.1% and for depression (PHQ-9≥10) were 73.8% and 70.9% in patients with cancer with an aggregate score of 35 or above.

CONCLUSIONS

Dignity is significantly correlated with personal demographic characteristics and psychological distress in patients with cancer. The results provide reference data for healthcare professionals to understand and enable dignity in patients with cancer and aid in the development of methods that promote their dignity.

Demoralization and Suicidal Ideation in Chronic Pain Patients

The literature has clearly stressed that patients suffering from chronic pain are at high risk of suicidal behavior (SB). Hence the need to improve the characterization of this behavior risk profile in these patients. Some findings indicate a possible relationship between demoralization and pain, with functional disability found to be correlated with demoralization. The primary objective of this study was to investigate the relationship between demoralization and suicidal ideation (SI) in patients with chronic pain. The secondary objective was to verify whether demoralization can occur independently of depression in these patients. Inclusion criteria were patients with chronic pain, with SI or not, matched for age and gender, aged > 18 years. Seventy patients with SI and 70 patients without SI were included. Between-group difference was statistically significant (F=1.064; t= 7.21, p<0.001, d=1.22), confirming the presence of numerous and intense depressive symptoms in the patients of the SI group. Regarding the Demoralization Scale (DS), the difference between the two groups was statistically highly significant (F=1.49; t=9.44; p<0.001, d=1.6). There was also a strong positive correlation between DS and Beck Depression Inventory (BDI-II) (R=0.749; p<0.001 for the study group and R=0.704; p<0.001 for the control group). Furthermore, there was a strong positive correlation between the DS and the Scale for Suicide Ideation (SSI) in the SI patients group, meaning that high demoralization is associated with higher suicidal ideation as well. Our findings did not allow us to distinguish between the notions of depression and demoralization, since the two constructs show almost the same strong positive correlation with suicidal thoughts, the two also being strongly correlated with each other.

Demoralization in suicide: A systematic review

OBJECTIVE

In psychiatric literature, few original studies exist on the topic of demoralization in suicide. In this review, we aim to identify original studies on suicidal ideation (SI)/suicidal behavior (SB) and demoralization in populations of community-dwellers and patients with somatic or psychiatric disorders.

METHODS

We employed a systematic approach that followed PRISMA guidelines, searching through four major electronic databases (PubMed/MEDLINE, Scopus, Science Direct, and PsychINFO) for relevant titles/abstracts published from January 1980-June 2021. We included original studies that explicitly mentioned the investigation of a potential association between SI/SB and demoralization.

RESULTS

A total of 18 studies met our inclusion criteria. Their synthesis revealed that demoralization can be associated with SI/SB in a wide range of populations (community dwellers, patients with somatic or psychiatric disorders) and lead to significantly higher suicide risk (odds ratios of >6 were encountered in community dwellers experiencing financial hardship or isolation). Moreover, demoralization alone (about half the patients who were demoralized did not meet the criteria for an affective disorder nor were they clinically depressed) or together with depression has been identified as a major risk factor for SI/SB. Regarding the crucial issue of progression from SI to SA, in the context of the "ideation-to-action" frame, some authors found that the interaction of demoralization and over-arousal could be a useful predictor for this progression, while others found that depression alone was sufficient to differentiate attempters from non-attempters or the interaction with shutdown (helplessness and low positive emotions).

CONCLUSION

These results emphasize the possibility to identify demoralization as an independent risk factor for suicide. In patients with psychiatric disorders, the association between demoralization and SI/SB may be transnosographic. Overall, from the clinical implications perspective, our findings highlight that: i. Assessment of demoralization may contribute to a more comprehensive suicide risk detection. This appears particularly relevant in Emergency Departments (EDs) where heterogeneous population typologies are usually admitted and a clinical diagnosis of depression is often difficult to be defined. ii. Additionally, since meaninglessness is considered one of the demoralization subcomponents, meaning-centered psychotherapeutic approaches prove to be indicated and they can be initiated already at the EDs upon first contact with the patient. Further studies are necessary to confirm these findings.

The Reliability and Test-Retest Stability of the Treatment Perception Questionnaire (TPQ) in the Oncology Field: A Pilot Study

Background:

Patients' satisfaction is an indicator of technical, instrumental, environmental, and interpersonal aspects of care. It shows how much the health service “as a whole organization” meets the patients’ psychosocial expectations and if the health professionals combine their technical competence with relational skills. The Treatment Perception Questionnaire (TPQ) is a brief instrument developed in the United Kingdom for research with substance abuse disorder populations. The present study aimed at evaluating the reliability and test-retest stability of the TPQ Italian translation in a sample of patients with solid and blood cancers.

Methods:

The TPQ was administered to 263 people with solid and blood cancers. Test-retest reliability was evaluated in a subgroup of 116 participants who completed the TPQ again after 3 months.

Results:

The reliability of TPQ was good. Cronbach’s alpha: 0.83 (95%CI: 0.79-0.86), 0.66 (0.59-0.72), 0.71 (0.65-0.769), respectively, in the total test, and in subscales on “staff perception”, and “program perception”. Test-retest reliability was 0.82 (0.77-0.87). The mean difference between the first and the second assessment was 1.0 (SD = 7.1; 95% CI -0.35 to 2.33). By plotting the differences and the means of the two assessments, 5/116 cases (4.3%) were outside the upper and lower limits of agreement.

Conclusions:

This study points out good reliability and test-retest stability of the TPQ in the oncology field. The TPQ can be used to assess variation over time about satisfaction with care in patients with oncological diseases, favoring the identification of unmet patients’ needs about the quality of the service.

Severe Suicidality in Athletes with Chronic Traumatic Encephalopathy: A Case Series and Overview on Putative Ethiopathogenetic Mechanisms

Chronic traumatic encephalopathy (CTE) results from repetitive brain injuries and is a common neurotraumatic sequela in contact sports. CTE is often accompanied by neuropsychiatric symptoms, which could escalate to suicidal ideation (SI) and suicidal behaviour (SB). Nevertheless, fairly limited emphasis about the association between suicidality and CTE exists in medical literature. Here, we report two cases of retired professional athletes in high contact sports (boxing and ice hockey) who have developed similar clinical trajectories characterized by progressive neuropsychiatric symptoms compatible with a CTE diagnosis and subsequent SB in its severe forms (medical serious suicide attempt (SA) and completed suicide). In addition to the description of outlining clinical, neuropsychological, neuroimaging, and differential diagnosis elements related to these cases, we also hypothesized some mechanisms that might augment the suicide risk in CTE. They include those related to neurobiological (neuroanatomic/neuroinflammatory) dysfunctions as well as those pertaining to psychiatry and psychosocial maladaptation to neurotraumas and retirement from professional competitive activity. Findings described here can provide clinical pictures to improve the identification of patients with CTE and also potential mechanistic insights to refine the knowledge of eventual severe SB development, which might enable its earlier prevention.

Psychosocial Dimensions in Hemodialysis Patients on Kidney Transplant Waiting List: Preliminary Data

Although the donation rate for deceased and living kidneys has been increasing, the donor organ availability meets only the 30% of kidney needs in Italy. Consequently, hemodialysis patients stay for a long time, an average of 3.2 years, on a waiting list for a kidney transplant with consequent relevant psychological distress or even full-fledged psychiatric disorders, as diagnosed with traditional psychiatric nosological systems. Recent studies report, however, a higher prevalence of other psychosocial syndromes, as diagnosed by using the Diagnostic Criteria for Psychosomatic Research (DCPR) in medically ill and kidney transplant patients. Nevertheless, no data regarding DCPR prevalence are available in patients waitlisted for a renal transplant (WKTs). Thus, the primary aim of this study was to identify sub-threshold or undetected syndromes by using the DCPR and, secondly, to analyze its relationship with physical and psychological symptoms and daily-life problems in WKTs. A total of 30 consecutive WKTs were assessed using the DCPR Interview and the MINI International Neuropsychiatric Interview 6.0. The Edmonton Symptom Assessment System (ESAS) and the Canadian Problem Checklist were used to assess physical and psychological distress symptoms and daily-life problems. A total of 60% of patients met the criteria for at least one DCPR diagnosis; of them, 20% received one DCPR diagnosis (DCPR = 1), and 40% more than one (DCPR > 1), especially the irritability cluster (46.7%), Abnormal Illness Behavior (AIB) cluster (23.3%) and somatization cluster (23.3%). Fifteen patients met the criteria for an ICD diagnosis. Among patients without an ICD-10 diagnosis, 77.8% had at least one DCPR syndrome (p < 0.05). Higher scores on ESAS symptoms (i.e., tiredness, nausea, depression, anxiety, feeling of a lack of well-being and distress), ESAS-Physical, ESAS-Psychological, and ESAS-Total were found among DCPR cases than DCPR non-cases. In conclusion, a high prevalence of DCPR diagnoses was found in WKTs, including those who resulted to be ICD-10 non-cases. The joint use of DCPR and other screening tools (e.g., ESAS) should be evaluated in future research as part of a correct psychosocial assessment of WKTs.

The Role of Demoralization and Meaning in Life (DEMIL) in Influencing Suicidal Ideation Among Patients Affected by Chronic Pain: Protocol of a Single-Center, Observational, Case-Control Study

BACKGROUND

Chronic pain is a significant risk factor for suicidal ideation (SI) and suicidal behavior (SB), including a 20%-40% prevalence rate of SI, a prevalence between 5% and 14% of suicide attempts, and a doubled risk of death by suicide in patients with chronic pain compared to controls. In most studies, associations between chronic pain and suicidality are robust, even after adjusting for the effect of sociodemographics and psychiatric comorbidity, and particularly for depressive conditions. A number of specific conditions that can modulate suicidality risk in patients with chronic pain have been investigated, but there is a need for their more specific characterization. Numerous recent studies have shown that demoralization and meaning in life (MiL) constructs affect suicidality as risk and protective factors, respectively. These constructs have been mainly investigated in patients with somatic illness and in community-dwelling individuals who may present with SI or SB independently of a psychiatric diagnosis of depression. However, a paucity of studies investigated them in suicidal patients affected by chronic pain.

OBJECTIVE

The primary objective of this project is to investigate the relationship between demoralization and MiL on SI risk in patients with chronic pain. The secondary objectives are (1) to test whether demoralization can occur independently of depression in patients with chronic pain and SI, (2) to examine whether the expected association between demoralization and SI may be explained by a sole dimension of demoralization: hopelessness, (3) to examine whether the presence of MiL, but not the search for MiL, is associated with less SI, and (4) to explore whether previously described MiL profiles (ie, high presence-high search, high presence-low search, moderate presence-moderate search, low presence-low search, and low presence-high search) emerge in our cohort.

METHODS

This project is a single-center, observational, case-control study-the Demoralization and Meaning in Life (DEMiL) study-conducted by the Division of Clinical Pharmacology and Toxicology, the Multidisciplinary Pain Centre, and the Service of Liaison Psychiatry and Crisis Intervention at the Geneva University Hospitals. Self- and hetero-administered questionnaires were conducted among patients and controls, matched by age and gender. The Ethics Committee of the Canton of Geneva approved the scientific utilization of collected data (project No. 2017-02138; decision dated January 25, 2018). Data have been analyzed with SPSS, version 23.0, software (IBM Corp).

RESULTS

From March 1, 2018, to November 30, 2019, 70 patients and 70 controls were enrolled. Statistical analyses are still in progress and are expected to be finalized in November 2020. To date, we did not observe any unfavorable event for which a causal relationship with the collection of health-related personal data could be ruled out. Results of this study are expected to form the basis for possible prevention and psychotherapeutic interventions oriented toward demoralization and MiL constructs for suicidal patients with chronic pain.

CONCLUSIONS

The interest in exploring demoralization and MiL in chronic pain patients with SI arises from the common clinical observation that experiencing chronic pain often requires a revision of one's life goals and expectations. Hence, the impact of chronic pain is not limited to patients' biopsychosocial functioning, but it affects the existential domain as well. The major clinical implications in suicidal patients with chronic pain consist in trying to (1) delineate a more precise and individualized suicide risk profile, (2) improve detection and prevention strategies by investigating SI also in individuals who do not present with a clinically diagnosed depression, and (3) enhance the panel of interventions by broadening supportive or psychotherapeutic actions, taking into consideration the existential condition of a person who suffers and strives to deal with his or her suffering.

Meaning in life and demoralization: a mental-health reading perspective of suicidality in the time of COVID-19

Consequences on mental health have been reported in general population, vulnerable individuals, psychiatric patients, and healthcare professionals. It is urgently necessary to study mental health issues in order to set priorities for public health policies and implement effective interventions. Suicidality is one of the most extreme outcomes of a mental health crisis. It is currently too early to know what the effect of COVID-19 will be on suicidality. However, authoritative commentary papers alert that most of the factors precipitating suicide are, and probably will be for a long time, present at several individual existence levels. A number of prevention measures and research considerations have been drawn up. A point of the latter, recommended by the International COVID-10 Suicide Prevention Research Collaboration, states that “the COVID-19 suicide research response should be truly multidisciplinary. This will foster research that addresses the different aspects and layers of risk and resilience […]. It will also foster research that informs prevention efforts by taking a range of perspectives” (Niederkrotenthaler et al., 2020). In this light, we would like to propose a reading perspective of suicidality that takes into account Meaning in Life (MiL) and demoralization. Both of the constructs were studied in heterogeneous populations with extreme life situations having led to a fracture between a “before” and an “after”, and play a role in affecting suicidality, respectively as resilience and risk factors. In clinical practice, during these unprecedent times, we wish that this more inclusive approach could: 1) contribute to prevention, by delineating more individualized suicidal risk profiles in persons conventionally non-considered at risk but here exposed to an extremely uncommon experience, 2) enrich supportive/psychotherapeutic interventions, by broadening the panel of means to some aspects constitutive of the existential condition of a person who is brutally confronted with something unexpected, incomprehensible and, in some ways, still unpredictable.

Meaning in Life and Demoralization Constructs in Light of the Interpersonal Theory of Suicide: A Trans-Theoretical Hypothesis for a Cross-Sectional Study

Following V. Frankl's (in the 1950s) and J. Frank's (in the 1970s) historical definitions of the constructs Meaning in Life (MiL) and demoralization, there have been a multitude of studies which have described them from different theoretical perspectives. These constructs are closely linked, with the lack of MiL as one of the subconstructs underlying the definition of demoralization. Numerous studies have shown that MiL and demoralization affect suicidality, as protective and risk factors, respectively. The Interpersonal Theory of Suicide (IPTS) is a more recent framework conceptualized by T. Joiner (in the 2000s) to provide an additional possible reading key in the effort to better understand suicidality. By analogy to a previous study by E. Kleiman & J. Beaver (2013), examining MiL and demoralization in suicidality through a perspective of the IPTS framework can be of considerable interest. This study showed, in a cohort of undergraduate students, that MiL mediated the relationship between two variables associated with IPTS (perceived burdensomeness and thwarted belongingness) and suicidal ideation (SI). Taking into consideration future studies that these latter authors advocated, our aim is to verify this finding using a cross-sectional study. Differences in our approach would include a) studying a clinical population (suicidal patients attending an emergency department), b) analyzing relationships not only with SI but also with suicidal attempts (SA), and c) in consideration of the interconnection between MiL and demoralization, exploring also the possible role of demoralization as a mediator. The clinical implication lies in identifying multi-faceted targets that may be useful to mitigate suicidality risk in individuals, both in prevention and therapy intervention.

Demoralization and Its Relationship with Depression and Hopelessness in Suicidal Patients Attending an Emergency Department

Emergency departments (EDs) play an increasingly crucial role in the management of patients with suicidal behavior (SB). Demoralization has been associated with SB in various populations and conditions, but little is known about the effect of this construct in SB patients who attend an ED. Therefore, a more inclusive SB assessment which considers the demoralization construct could be useful in clinical practice. The main aim of this study was to assess the presence and severity of demoralization in patients visiting EDs for SB. Secondly, the maintenance of the relationship between demoralization and SB after controlling for depression and the proportion of variance which accounted for hopelessness was investigated. A cross-sectional study of patients (N = 199) visiting an ED for SB was performed, which examined the role of demoralization, hopelessness, and depression on suicidal ideation (SI) and suicide attempts (SAs). Demoralization was strongly and positively correlated with SI. Demoralization was related to major depressive episodes, but it was confirmed to be a different and, probably, more sensitive construct for SB, validating its specificity in relation to depression. Hopelessness accounted for a small portion of the variance in SI, compared to demoralization. Formal support for the association of demoralization with SI was provided. Demoralization can improve SB assessment in EDs, particularly among patients whose suicide risk can be unnoticed. Furthermore, demoralization represents a clinically useful concept to increase comprehension of the suffering of the suicidal patient and a possible target for psychotherapeutic interventions.

Relationships among Lifestyle, Depression, Anxiety, and Reproductive Health in Female University Students

PURPOSE

To identify relationships among lifestyle, psychological distress, and reproductive health in female university students.

METHODS

We used a descriptive cross-sectional design. A total of 275 subjects were enrolled. Subjects agreed to undergo a face-to-face interview, including administration of structured questionnaires to determine health promotion lifestyle profile II (HPLP-II), depression anxiety stress scale for depression and anxiety (DASS-D, DASS-A), and reproductive health (knowledge, attitude, behavior, menstruation irregularity, dysmenorrhea, and gynecologic symptoms).

RESULTS

The mean age of subjects was 21.2 years. Those with low HPLP-II score showed significantly high menstruation irregularity. Those with high depression and anxiety had significantly high reproductive symptoms. In addition, high HPLP-II score was correlated with low depression, anxiety, and high reproductive health.

CONCLUSION

The life style of female university students is associated with depression, anxiety, and reproductive health. To improve female university students' reproductive health, life style interventions including healthy nutritional habit, physical activity, and stress management are important.

Association of Anxiety, Depression, and Somatization with Menstrual Problems among North Korean Women Defectors in South Korea

OBJECTIVE

North Korean women defectors have suffered from anxiety, depression, and somatization after defection. Also they have had many menstrual problems like amenorrhea. This study was done to identify the correlations of anxiety, depression, and somatization to menstrual problems among North Korean woman defectors in South Korea.

METHODS

The participants in this study were 126 women from 5 government resettlement centers throughout South Korea. Questionnaires which included State-Trait Anxiety Inventory (STAI), Center for Epidemiological studies-Depression Scale (CED-S), and Symptom Checklist-90-Revised (SCL-90-R) were used to identify anxiety and somatization. Data were collected between June and September, 2012.

RESULTS

The women reported the following problems; amenorrhea (9.5%), hypomenorrhea (13.6%), menorrhagia (19.8%), polymenorrhea (13.5%), oligomenorrhea (4.8%), changes in amount of menstrual discharge (4.0%), and changes in amount of blood clot (9.5%). Anxiety (r=0.20, p=0.002), depression (r=0.25, p=0.005), and Somatization (r=0.35, p<0.001) were correlated with number of menstrual problems.

CONCLUSION

The results of this study indicate that mental health services need to be taken into account in interventions for North Korean woman defectors to improve their reproductive health including addressing menstrual problems.

An exploratory study comparing psychological profiles and its congruence with clinical performance among patients with functional or motility digestive disorders

Functional gastrointestinal disorders have been related with different psychological conditions. On the contrary, the role of psychological factors within gastrointestinal motor disorders remains unclear. The objective of this study was to explore the differences and congruence with clinical performance of the psychological profile and subjective functionality among patients diagnosed with functional gastrointestinal disorders and gastrointestinal motor disorders. Using a double-blind design, 56 inpatients from a Gastroenterology Department were included in the study. No major differences were detected between the two groups. However, clinical performance was coherent with subjective physical functioning only among patients diagnosed with gastrointestinal motor disorders. These results may provide useful information for gastroenterologists dealing with patients' complaints not consistent with their clinical profile.

Demoralisation syndrome does not explain the psychological profile of community-based asylum-seekers

BACKGROUND

Demoralisation syndrome (DS) has been advanced as a construct that features hopelessness, meaninglessness, and existential distress. Demoralisation and DS have predominantly been considered secondary only to illness; hence there is scant research on demoralisation or DS in populations affected by extreme environmental stress.

AIMS

The current study aimed to determine the prevalence of demoralisation, its predictors, and the relevance of DS in a community-based forced-migrant population.

METHOD

A convenience sample of 131 adult asylum-seekers (n=98) and refugees (n=33) without recognised mental disorders in Melbourne, Australia, were assessed cross-sectionally on posttraumatic stress, anxiety, depression, post-migration stress, and demoralisation. Socio-demographic data were analysed with relevant clinical data. Predictive aims were investigated using bivariate statistical tests and exploratory aims were investigated using correlational and linear regression analyses.

RESULTS

Seventy nine percent of the sample met criteria for demoralisation (asylum-seekers=83%; refugees=66%), with asylum-seekers being 2.55 (95% C.I.=1.03-6.32, Z=2.03, p=.04) times more likely to be demoralised than refugees. No relationship between demoralisation and time in the refugee determination process emerged. The regression model explained 47.5% of variance in demoralisation scores for the total sample F(9,111)=13.07, p<.0001, with MDD and anxiety score making unique significant contributions.

CONCLUSIONS

Demoralisation was widespread through the asylum-seeker and refugee population and its prevalence was attributable to a range of social and psychiatric factors. However, DS had little explanatory power for psychiatric morbidity, which was more suggestive of a pan-distress symptom complex.

Demoralization: a systematic review on its clinical characterization

BACKGROUND

Demoralization has been described as a psychological state characterized by helplessness, hopelessness, a sense of failure and the inability to cope.

METHODS

We conducted a systematic review with qualitative data analysis following PRISMA criteria with the following aims: to review validated assessment instruments of the demoralization syndrome, report main findings regarding demoralization as measured by validated instruments that emerge in the literature, compare and report evidence for the clinical utility of the identified instruments. Utilizing the key word 'demoralization' in PubMed and PsycINFO databases, an electronic search was performed, supplemented by Web of Science and manual searches. Study selection criteria included the assessment of medical patients and use of instruments validated to assess demoralization. Seventy-four studies were selected.

RESULTS

Four instruments emerged in the literature. Main findings concern prevalence rates of demoralization, evidence of discriminant validity from major depression, factors associated with demoralization and evidence of clinical utility. The instruments vary in their definition, the populations they aim to assess, prevalence rates they estimate and their ability to discriminate between different conditions. Nonetheless, demoralization appears to be a distinctive psychological state characterized by helplessness, hopelessness, giving up and subjective incompetence. It is not limited to life-threatening diseases such as cancer, but may occur in any type of clinical situation. It is associated with stress and adverse health outcomes.

CONCLUSIONS

Studies addressing the incremental value of demoralization in psychiatry and psychology are needed. However, demoralization appears to entail specific clinical features and may be a distinct condition from major depression.

Clinimetrics and clinical psychometrics: macro- and micro-analysis

BACKGROUND

Clinimetrics was introduced three decades ago to specify the domain of clinical markers in clinical medicine (indexes or rating scales). In this perspective, clinical validity is the platform for selecting the various indexes or rating scales (macro-analysis). Psychometric validation of these indexes or rating scales is the measuring aspect (micro-analysis).

METHODS

Clinical judgment analysis by experienced psychiatrists is included in the macro-analysis and the item response theory models are especially preferred in the micro-analysis when using the total score as a sufficient statistic.

RESULTS

Clinical assessment tools covering severity of illness scales, prognostic measures, issues of co-morbidity, longitudinal assessments, recovery, stressors, lifestyle, psychological well-being, and illness behavior have been identified.

CONCLUSION

The constructive dialogue in clinimetrics between clinical judgment and psychometric validation procedures is outlined for generating developments of clinical practice in psychiatry.

An emerging dimension in psychosomatic research: the nocebo phenomenon in the management of chronic pain

Introduction. The nocebo effect consists in delivering verbal suggestions of negative outcomes so that the subject expects clinical worsening. Several studies indicate that negative verbal suggestions may result in the amplification of pain. Amplification style is one of the most important dimensions in psychosomatic research. Methods. One group of pain therapy unit patients was evaluated at baseline and again after 6 months from the beginning of the pain treatment. Results. Only 43% of 86 chronic pain patients respond positively to the expectation of sham pain. This group shows at baseline higher pain intensity (t value: 2.72, P = 0.007) and lower cold pain threshold (t value: 2.18, P = 0.03) than the group of subjects with any response to sham pain stimulus. Somatoform dimensions influence positively the strength of nocebo response in those predisposed to it. Conclusion. Our study shows that the power of the nocebo phenomenon seems to be a dimension belonging to the investigation in psychosomatic. In contrast to what one might expect, the presence of the nocebo phenomenon affects positively pain relief and the outcome of pain treatment. In a clinical setting, and the meaning of nocebo response does not seem to be different from placebo response.

Somatization and somatic symptom presentation in cancer: a neglected area

Abstract The recognition of somatization process in cancer patients is a challenging and neglected area, for the extreme difficulty in differentiating and assessing the psycho(patho)logical components from those biologically determined and related to cancer and cancer treatment, as well as for the scarce usefulness of rigid categorical DSM criteria. However, several dimensions of somatization (and the interconnected concept of abnormal illness behaviour) have been shown to be diagnosable in cancer patients and to negatively influence coping and quality of life outcomes. An integration of the formal DSM-ICD nosology with a system specifically taking into account the patients' emotional responses to cancer and cancer treatment, such as the Diagnostic Criteria for Psychosomatic Research (DCPR), is suggested. More data on some specific symptom dimensions, including pain, fatigue and sexual disorders, are needed to examine their possible psychological components. More research is also needed regarding the association of somatization with personality traits (e.g. type D distressed personality, alexithymia), developmental dimensions (e.g. attachment), and cultural issues (e.g. culturally mediated attributional styles to somatic symptoms). Also, the impact and effectiveness of specific therapeutic intervention in 'somatizing' cancer patients is necessary.

Psychosomatic syndromes and anorexia nervosa

BACKGROUND

In spite of the role of some psychosomatic factors as alexithymia, mood intolerance, and somatization in both pathogenesis and maintenance of anorexia nervosa (AN), few studies have investigated the prevalence of psychosomatic syndromes in AN. The aim of this study was to use the Diagnostic Criteria for Psychosomatic Research (DCPR) to assess psychosomatic syndromes in AN and to evaluate if psychosomatic syndromes could identify subgroups of AN patients.

METHODS

108 AN inpatients (76 AN restricting subtype, AN-R, and 32 AN binge-purging subtype, AN-BP) were consecutively recruited and psychosomatic syndromes were diagnosed with the Structured Interview for DCPR. Participants were asked to complete psychometric tests: Body Shape Questionnaire, Beck Depression Inventory, Eating Disorder Inventory-2, and Temperament and Character Inventory. Data were submitted to cluster analysis.

RESULTS

Illness denial (63%) and alexithymia (54.6%) resulted to be the most common syndromes in our sample. Cluster analysis identified three groups: moderate psychosomatic group (49%), somatization group (26%), and severe psychosomatic group (25%). The first group was mainly represented by AN-R patients reporting often only illness denial and alexithymia as DCPR syndromes. The second group showed more severe eating and depressive symptomatology and frequently DCPR syndromes of the somatization cluster. Thanatophobia DCPR syndrome was also represented in this group. The third group reported longer duration of illness and DCPR syndromes were highly represented; in particular, all patients were found to show the alexithymia DCPR syndrome.

CONCLUSIONS

These results highlight the need of a deep assessment of psychosomatic syndromes in AN. Psychosomatic syndromes correlated differently with both severity of eating symptomatology and duration of illness: therefore, DCPR could be effective to achieve tailored treatments.

Entwicklung und Validierung eines Fragebogens zur Erfassung von hypochondrischem Sicherheitsverhalten

Theoretischer Hintergrund: Sicherheitsverhalten wird für die Aufrechterhaltung von hypochondrischen Ängsten ein wichtiger Stellenwert beigemessen. Fragestellung: In der vorliegenden Untersuchung soll die Güte eines Fragebogens zur Erfassung von Sicherheitsverhalten bei vorliegender Hypochondrie (FSVH) überprüft werden. Methode: Zur Validierung wurden eine Patientenstichprobe (N = 108) und eine Online-Stichprobe (N = 503) herangezogen. Ergebnisse: Mittels explorativer und konfirmatorischer Faktorenanalysen ließen sich die Faktoren Rückversicherungs- und Vermeidungsverhalten extrahieren. Es zeigten sich deutliche Hinweise für die konvergente und diskriminante Validität des FSVH. Für den FSVH fanden sich signifikant höhere Werte für Patienten mit Hypochondrie als für solche mit Angststörungen, somit war es möglich, mittels des FSVH zwischen diesen beiden Störungsgruppen mit hoher Genauigkeit zu diskriminieren. Schlussfolgerung: Der FSVH stellt eine geeignete Ergänzung zu etablierten Verfahren dar.

Dysfunctional beliefs about symptoms and illness in patients with hypochondriasis

BACKGROUND

The cognitive model and empirical research underline the importance of dysfunctional beliefs about bodily symptoms and illness in health anxiety and hypochondriasis. However, specificity of such beliefs has not yet been adequately demonstrated for patients with hypochondriasis.

OBJECTIVE

This study examined whether dysfunctional beliefs about bodily symptoms and illness are elevated in comparison to patients with anxiety disorders and, therefore, specific for patients with hypochondriasis.

METHOD

Patients with hypochondriasis (n = 38), patients with anxiety disorders (n = 40), and healthy controls (n = 42) completed the Symptom and Outcomes Scale (SOS) measuring participants' estimation of the likelihood of various symptoms being indicative of a particular illness. Additionally, participants' general psychopathology (Brief Symptom Inventory), depressive (Beck Depression Inventory-II), and anxiety symptoms (Beck Anxiety Inventory) were evaluated.

RESULTS

In comparison to patients with anxiety disorders and healthy controls, patients with hypochondriasis estimated bodily symptoms to be more likely an indicator for a catastrophic illness. Patients with anxiety disorders took a middle position between patients with hypochondriasis and healthy controls. Regarding the estimation of the likelihood of symptoms indicating a minor illness, no differences were found between the three groups.

CONCLUSIONS

Dysfunctional beliefs about symptoms and illness are important and specific for patients with hypochondriasis, which is in line with the cognitive model. In order to reduce misinformation about serious illnesses in patients with hypochondriasis, more attention should be paid to psychoeducational strategies.

A cluster analysis-derived classification of psychological distress and illness behavior in the medically ill

BACKGROUND

The classification of psychological distress and illness behavior in the setting of medical disease is still controversial. Current psychiatric nosology does not seem to cover the spectrum of disturbances. The aim of this investigation was to assess whether the joint use of DSM-IV categories and the Diagnostic Criteria for Psychosomatic Research (DCPR), that provide identification of syndromes related to somatization, abnormal illness behavior, irritable mood, type A behavior, demoralization and alexithymia, could yield subtyping of psychosocial variables in the medically ill.

METHOD

A cross-sectional assessment using both DSM-IV and the DCPR was conducted in eight medical centers in the Italian Health System. Data were submitted to cluster analysis. Participants were consecutive medical out-patients and in-patients for whom a psychiatric consultation was requested. A total of 1700 subjects met eligibility criteria and 1560 agreed to participate.

RESULTS

Three clusters were identified: non-specific psychological distress, irritability and affective disturbances with somatization.

CONCLUSIONS

Two-step cluster analysis revealed clusters that were found to occur across clinical settings. The findings indicate the need of expanding clinical assessment in the medically ill to include the various manifestations of somatization, illness behavior and subclinical distress encompassed by the DCPR.

Current debates over nosology of somatoform disorders

There is a wide debate among the researchers and clinicians over the diagnostic categories subsumed under the rubric of somatoform disorders (SDs). Recent proposals vary from radical views that call for removing this category altogether to the conservative views that suggests cosmetic changes in the diagnostic criteria of SDs. We have the reviewed the relevant literature through PUBMED search supplemented with manual search on current concepts of SD.

Sarcoidosis: Psychotherapy and Long-Term Outcome—A Case Report

Sarcoidosis is a systemic, inflammatory disease of unknown aetiology, influenced by stressful life events and associated with a high incidence of alexithymic personality traits, and of depressive symptoms. The medical literature on sarcoidosis has called for a psychotherapeutic intervention to modify the perceived state of disease, the influence of stressful events and the depressive condition. Few studies have described cases treated with psychotherapy, and no information is available on its long-term outcome. We present the case of a patient with chronic sarcoidosis and periodical reacutizations with constantly pathological ESR. Twenty-four years after the diagnosis, a dynamic supportive-expressive psychotherapy for psychosomatic alexithymic patients was added to the medical therapy. At the beginning and at the end of the psychotherapy, and for the long-term outcome evaluations, Kellner's symptom questionnaire (SQ) was used to investigate psychological distress. The SQ scores, initially pathological, were normal at the end of the psychotherapy and for the following three years. Psychotherapy, without antidepressive drugs, resolved the depression. The depressive symptoms disappeared, along with the normalization and stabilization of the ESR. After three years, the outcome was positive. This is the first study describing a successful psychotherapy and its long-term outcome on a patient with sarcoidosis.

Subtyping depression in the medically ill by cluster analysis

BACKGROUND

There is increasing awareness of the need of subtyping major depressive disorder, particularly in the setting of medical disease. The aim of this investigation was to use both DSM-IV comorbidity and the Diagnostic Criteria for Psychosomatic Research (DCPR) for characterizing depression in the medically ill.

METHODS

1700 patients were recruited from 8 medical centers in the Italian Health System and 1560 agreed to participate. They all underwent a cross-sectional assessment with DSM-IV and DCPR structured interviews. 198 patients (12.7%) received a diagnosis of major depressive disorder. Data were submitted to cluster analysis.

RESULTS

Two clusters were identified: depressed somatizers and irritable/anxious depression. The somatizer cluster included 58.6% of the cases and was characterized by DCPR somatization syndromes (persistent somatization, functional somatic symptoms secondary to a psychiatric disorder, conversion symptoms, and anniversary reactions) and DCPR alexithymia. The anxious/irritable cluster had 41.4% of the total sample and included DCPR irritable mood and type A behavior and DSM-IV anxiety disorders.

LIMITATIONS

The study has limitations due to its cross-sectional nature. Further, these findings require additional validation in another sample.

CONCLUSIONS

The findings indicate the need of expanding clinical assessment in the medically ill to include the various manifestations of somatization, irritable mood, type A behavior and alexithymia, as encompassed by the DCPR. Subtyping major depressive disorder may yield improved targets for psychosomatic research and treatment trials.

Relationship between a hopeful attitude and cellular immunity in patients with breast cancer

OBJECTIVES

To evaluate the relationship between hopefulness and immune function in patients with breast cancer.

METHODS

A total of 196 patients with breast cancer were enrolled. The subjects were divided into two groups using the abbreviated version of the seven-item Beck Hopelessness Scale (BHS-7). Subsets of circulating lymphocytes were assessed using flow cytometry: CD3(+), CD4(+), CD8(+), CD19(+) and CD56(+). The Beck Depression Inventory (BDI), Montgomery-Asberg Depression Rating Scale (MADRS) and EORTC QLQ-C30 were administered.

RESULTS

A total of 104 patients (53.6%) showed a hopeful attitude, with a score of 0 on the BHS-7. Scores on the MADRS and BDI were significantly higher in the nonhopeful group, whereas global and total functioning scores on the EORTC QLQ-C-30 were significantly higher in the hopeful group. The hopeful group showed significantly higher CD8(+) T-cell percentage and counts and significantly lower CD4(+) T-cell percentage and CD19(+) B-cell percentage and counts compared with the nonhopeful group. All statistically significant differences between the two groups were maintained after adjusting for age and scores on the BDI and EORTC QLQ-C-30 as covariates, except for CD 19(+) cell counts.

CONCLUSION

The results suggest that hopefulness may be associated with immunity in patients with breast cancer, independent of depression and quality of life.

Factors associated with attributions about child health conditions and social distance preference

In order to better understand factors that account for the emergence and persistence of negative attitudes towards mental health problems, attributions about and stigma towards children's mental and physical illnesses were examined using National Stigma Study-Children data. Parent blame attributions were most strongly associated with attention deficit disorder, environmental causes with depression, and biology with asthma. Parent blame was more frequent for mental than physical health conditions. Child blame was associated with higher preferred social distance from the child, but no clear links were observed between social distance and attributions about genetic/biology, environment, or parent blame. Rurality was not significantly associated with attributions or social distance preference. Higher educational achievement was associated with increased endorsement of environmental stress factors and reduced odds of child blaming. The general public holds complex explanatory models of and nuanced responses to children's mental disorders that need further investigation, including effects on parents' and children's help-seeking.

Somatoform disorders: 30 years of debate about criteria! What about children and adolescents?

OBJECTIVES

The aim of this study was to evaluate the suitability of the complex somatic symptom disorder, proposed by the DSM-V Somatic Symptom Disorders Workgroup, in classifying children and adolescents who suffer severely from medically unexplained symptoms.

METHODS

The existing knowledge about somatoform disorders (SDs) in children and adolescents was delineated by means of a comprehensive search in the psychological, psychiatric, and pediatric literature. It was analyzed to assess whether children and adolescents suffer from SDs according to DSM-IV-TR (prevalence, developmental course, comorbidity, risk factors, and impact on daily functioning). Subsequently, each criterion of the complex somatic symptom disorder was outlined and discussed with respect to its suitability in classifying children and adolescents. The suitability of the DSM-IV-TR criteria of SDs and that of the criteria of the complex somatic symptom disorder were compared.

RESULTS

Current data of sufficient quality are limited but indicate that the DSM-IV-TR criteria are inappropriate for classifying most children and adolescents suffering from somatoform symptoms. The criteria for complex somatic symptom disorder are more appropriate. Nevertheless, it is recommended to include two additional parameters: "parental excessive concern and preoccupation with the child's symptoms" and "high parental health anxieties."

CONCLUSIONS

The criteria for complex somatic symptom disorder are more appropriate for children and adolescents than the current DSM-IV-TR criteria; they should be better adapted to the special situation of children and adolescents.

Are psychological features useful in classifying patients with somatic symptoms?

OBJECTIVE

To evaluate psychological characteristics that could be used for the classification of somatic syndromes requesting medical care. Positive psychological classification criteria are needed to justify the classification of somatic syndromes as Diagnostic and Statistical Manual of Mental Disorders- or International Classification of Diseases-10 section F/mental disorders diagnosis.

METHODS

From a population-based sample of 2510 people, subsamples reporting high scores for somatic symptoms (SOM+; n = 154) versus average scores for somatic symptoms (SOM-; n = 167) were defined. Telephone interviews (e.g., structured interviews for diagnoses, healthcare use, symptom history, possible psychological characteristics), self-rating scales (e.g., Pain Disability Index, depression scale Patient Health Questionnaire-9), and general practitioners reports were collected for these subsamples. In addition to somatic symptoms, we used healthcare use and disability as major external validation criteria.

RESULTS

There was strong evidence for ten of the 28 binary coded psychological variables to identify those people with somatic symptoms who needed medical help and/or were seriously disabled. These variables included "avoidance of physical activities," "bias for somatic illness attributions," "self-concept of being physically weak," and "desperation because of somatic symptoms." The relevance of these psychological characteristics was partially further confirmed by stepwise regression analyses, which showed incremental validity compared with variables like somatic symptoms and depression.

CONCLUSIONS

This study identified several psychological characteristics of people with somatic complaints who need medical care. These features can be assessed, using binary variables that are more feasible for classification processes. These psychological criteria should be included in classification rules for people with somatic syndromes (e.g., somatoform disorders).

Psychosomatic medicine

Psychosomatic medicine may be defined as a comprehensive, interdisciplinary framework for: assessment of psychological factors affecting individual vulnerability as well as course and outcome of illness; biopsychosocial consideration of patient care in clinical practice; specialist interventions to integrate psychological therapies in the prevention, treatment and rehabilitation of medical disease. The aim of this review was to provide an updated definition of psychosomatic medicine, to outline its boundaries with related disciplines and to illustrate its main contributions to clinical and preventive medicine. A review of the psychosomatic literature, using both Medline and manual searches, with particular reference to articles, which could be relevant to clinical practice, was performed. Current advances in the field have practical implications for medical research and practice, with particular reference to the role of lifestyle, the challenge of medically unexplained symptoms, the psychosocial needs entailed by chronic illness, the appraisal of therapy beyond pharmaceutical reductionism, the function of the patient actively contributing to his/her health. Today, the field of psychosomatic medicine is scientifically rigorous, more diversified and therapeutically relevant than ever before.

Psychosomatic medicine is a comprehensive field, not a synonym for consultation liaison psychiatry

There is controversy surrounding the term psychosomatic. If it is used as an equivalent of consultation liaison psychiatry, there is little justification for retaining it. Psychosomatic medicine, however, may be defined as a comprehensive interdisciplinary framework for the assessment of psychosocial factors affecting individual vulnerability, course, and outcome of any type of disease; holistic consideration of patient care in clinical practice; and integration of psychological therapies in the prevention, treatment, and rehabilitation of medical disease. Psychosomatic medicine has developed several clinimetric tools for assessing psychosocial variables in the setting of medical disease and has raised the need for specific evaluations in medical assessment. The term psychosomatic medicine today seems to be more timely than ever and provides a home for innovative and integrative thinking at the interface of behavioral and medical sciences.

Comorbidity between common mental disorders and chronic somatic diseases in primary care patients

OBJECTIVE

To estimate the prevalence of the most common mental disorders in primary care patients with chronic somatic diseases based on physicians' diagnoses and compared with healthy probands.

METHOD

A systematic sample of 7940 adult primary care patients was recruited by 1925 general practitioners (GPs) in a large cross-sectional national epidemiological study. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used as standardized instrument for the assessment of mental disorders. Medical diagnoses were provided by patient's GP.

RESULTS

The prevalence rate of mental disorder was significantly higher in patients with chronic somatic diseases (56.8%) compared with physically healthy subjects (48.9%; OR: 1.37). Prevalence of depressive and anxiety disorders is higher among individuals with neurological, oncological or liver disease. The differences are significant in all comparisons, with the exception of anxiety disorders in patients with musculoskeletal disorders. There is an increase in prevalence rates of mental disorders according to the number of somatic diseases.

CONCLUSIONS

The study provides evidence of the comorbidity of common mental disorders and somatic diseases. We need a predominant focus on affective and anxiety disorders in primary care patients with chronic somatic diseases. Symptoms overlap makes it necessary to discriminate these differences more in detail in future studies.

Non-fearful panic disorder in gastroenterology

BACKGROUND

Nonfearful panic disorder (NFPD) is a panic condition masked under the appearance of somatic symptoms only, without the component of fear, and it represents a challenging diagnostic task.

METHOD

This is the first case report of NFPD in a male patient with acute gastric pain and gastrointestinal disease (atrophic gastritis and H. pylori infection).

RESULTS

The patient showed atypical panic symptoms and demoralization on the Diagnostic Criteria for Psychosomatic Research screening. He was successfully treated with anti-panic medication and cognitive-behavioral therapy.

DISCUSSION

The case report shows that accurate psychosomatic assessment may help clinicians avoid diagnostic delay, prevent the administration of unnecessary medications, and give patients more appropriate treatment.

Advances in understanding illness anxiety

Illness anxiety, also known in its more severe form as hypochondriasis, is a debilitating and chronic condition in which normal bodily symptoms are misinterpreted as signs of serious medical illness. Patients suffer with the fear that they are ill despite reassurance to the contrary and often overuse medical services in the process. This article critically evaluates the recent literature on illness anxiety and related, medically unexplained symptoms, highlighting new and interesting findings in the areas of prevalence, classification/diagnosis, management, and evidence-based treatment and new frontiers in understanding illness anxiety, such as brain imaging, neuroimmunology, and cyberchondria.

[Somatoform disorders. Clinical evidence, etiology, pathogenesis, and therapy]

Patients presenting with bodily symptoms and complaints that are not explained by organic pathology or well-known pathophysiological mechanisms comprise a major challenge to any medical care system. From a perspective of psychiatric classification, such medically unexplained somatic symptoms are diagnosed as depressive and anxiety disorders on the one hand or somatoform disorders on the other. In clinical physical medicine a quite different diagnostic approach is taken to conceptualize functional somatic syndromes. Concepts of somatoform disorders are outlined, critical issues regarding existing diagnostic systems are discussed, and possible alternative approaches for upcoming versions of DSM-V and ICD-11 are mentioned. The main somatoform disorders are described in their clinical characteristics. Etiopathogenetically, somatoform disorders may best be considered within a multifactorial model. Some pragmatic guidelines for multimodal treatment of somatoform disorders are outlined.

Stress-induced differences in primary and secondary resistance against bacterial sepsis corresponds with diverse corticotropin releasing hormone receptor expression by pulmonary CD11c+ MHC II+ and CD11c- MHC II+ APCs

Stress responses have been associated with altered immunity and depending upon the type of stressor, can have diverse effects on disease outcomes. As the first line of defense against potential pathogens, alterations in cellular immune responses along the respiratory tract can have a significant impact on the manifestation of local and systemic disease. Utilizing a murine model of respiratory pneumonia, the current study investigated the effects of restraint stress on the induction of primary and secondary immunity along the respiratory tract, influencing host susceptibility. Female CD-1 mice were subjected to three hours of restraint stress over a period of four days followed by primary and secondary Streptococcus pneumoniae infection via intranasal route. Stress exposure led to increased retention of bacterial carriage in the lungs, enhanced polymorphonuclear cells and a preferential decrease in pulmonary CD11c(+) MHC II(+) cells resulting in delayed lethality during primary infection but significant impairment of acquired immune protection after secondary infection. We also provide evidence to support a role for lung-associated corticotropin releasing hormone regulation through peripheral CRH and diverse CRH receptor expression by MHC II(+) antigen presenting cells (APCs). We conclude that repeated restraint stress has distinct influences on immune cell populations that appear to be important in the generation of innate and adaptive immune responses along the respiratory tract with the potential to influence local and systemic protection against disease pathogenesis.

Cultural models and somatic syndromes

OBJECTIVES

To review the relevance of cultural models in the generation and amplification of somatic symptoms and syndromes.

METHODS

Based on a selective review of literature, we examine evidence that cultural and personal explanatory models can contribute to the pathogenesis, symptomatology, and chronicity of medically unexplained symptoms and functional somatic syndromes.

RESULTS

In the contemporary world, culture involves flows of information, roles, and institutions that offer individuals multiple models for understanding illness. Cultural models include 1) explanatory models, which make causal attributions and impute specific mechanisms or processes of pathophysiology; 2) prototypes, which are salient images or exemplars drawn from personal experience, family, friends, mass media, and popular culture that are used to reason analogically about one's own condition; and 3) implicit models and procedural knowledge that may be difficult to articulate because they are embedded in body practices and ways of experiencing distress. Symptom attributions and explanations can participate in vicious circles of symptom amplification that give rise to culture-specific varieties of panic disorder, hypochondriacal worry, and medically unexplained symptoms.

CONCLUSIONS

Clinical research using the methods of experimental cognitive and social psychology as well as community-based ethnographic and ecological research are needed to advance our understanding of the impact of personal and cultural models on somatic distress. Nevertheless, the current state of knowledge on social and cultural dimensions of somatic syndromes suggests a typology of forms of psychosomatic and sociosomatic looping that has implications for the nosology of somatoform disorders.
